You are right, it's better to clarify, in these cases (life-threatening) maximum seriousness is needed don't underestimate. I have a co detector, actually 2, but one is only for values after 150 ppm, while the other is more sensitive, it detected me 15-20 ppm even 50 in the morning when the air was too closed ( in the past ).
But now, and during combustion, I noticed a slight discomfort, but the co detector detects nothing. I got to thinking, which since I use a lot of air probably there is no co but there are other combustion products that cause discomfort, with the house under negative pressure, due to the new doors. Regarding the open window test, it was a test, which made me understand, Why do I have to open very large holes after I seal the house to make the stove work properly? Better to transfer the negative pressure, via oak, in the garage, which has 2 air vents. And that's what I'm doing, but a small air passage in the stove room is always good, even in the case of activation of the kitchen extractor and I repeat, at each reload, in general it would be useful to open the window, and close it immediately afterwards, to ensure that the open door of the stove does not cause episodes of negative pressure, which in practice cause turbulence, and a little smoke comes out at times. But that probably doesn't matter, without oak, the air would be exchanged quickly.
It is good to trust digital tools, but I think the sensations are even more valid.
